采用EHLA技术在45钢基材上制备TiC/IN625纳米复合涂层。分析不同热处理温度(800,1000 ℃和1200 ℃)对TiC/IN625涂层微观组织、表面形貌、残余应力和耐腐蚀性的影响。结果表明:随着热处理温度的提升,涂层偏析现象得到缓解。较HT0和HT800涂层,HT1000涂层中的Ti元素分布更加均匀。HT0涂层中的部分Laves相在HT1000涂层中开始溶解,释放出Nb元素,与C元素和Ti元素重新结合生成MC(M=Nb,Ti)碳化物。HT1200涂层表面微观组织中大尺寸的碳化物溶解,Ti元素和Ni等其他元素分布更加均匀,并向枝晶间区域扩散。HT0涂层表面残余应力主要表现为残余拉应力,其最大值为362 MPa。电化学腐蚀实验表明,开路电位由HT0涂层的-0.139 V提高到HT1200涂层的 -0.132 V。HT800,HT1000,HT1200涂层的电荷转移电阻(Rct)比HT0涂层更大,相较于HT0涂层的4.785×10~5 Ω·cm~2分别提高了46.2%,31.2%和64.3%。 |

The TiC/IN625 coatings were prepared on 45 steel substrates by using extreme-high-speed laser cladding(EHLA) technology. The effect of different heat treatment temperatures(800, 1000 ℃ and 1200 ℃) on the microstructure, surface morphology, residual stress and corrosion resistance of TiC/IN625 coatings was analyzed. The results show that the coating segregation phenomenon is alleviated with the increase of heat treatment temperature. The distribution of Ti elements in the HT1000 coating is more uniform than that in the HT0 and HT800 coatings. The part Laves phase in the HT0 coatings starts to dissolve in the HT1000 coatings, releasing Nb elements that recombine with C and Ti elements to generate MC (M=Nb, Ti) carbides. The large-sized carbides in the microstructure of HT1200 coatings surface dissolve. The other elements, such as Ti and Ni, more homogeneously distribute and diffuse into the interdendritic region. The residual stress on the HT0 coatings surface is mostly expressed as residual tensile stress, with a maximum value of 362 MPa. The electrochemical corrosion tests indicate that the opencircuit potential is increased from -0.139 V for the HT0 coatings to -0.132 V for the HT1200 coatings. The charge transfer resistance(Rct) of HT800,HT1000 and HT1200 coatings is also larger than that of the HT0 coatings, with an increase of 46.2%, 31.2% and 64.3% compared to the HT0 coating’s 4.785×10~5 Ω·cm~2, respectively. |
